--------------------------------
Hi, [~lilingzj].
These metrics are supported from 2.8.0 in YARN-3467, and 2.7.7 was already
released for a year.
I think it's unnecessary to launch a new issue for this, I suggest you upgrade
cluster or backport the patch in YARN-3467 for yourself. Of course, if there's
a release plan for 2.7.8, you can propose to backport it in YARN-3467.
> No allocatedMB, allocatedVCores, and runningContainers metrics on running

> Key: YARN-9632
> URL: https://issues.apache.org/jira/browse/YARN-9632
> Project: Hadoop YARN
> Issue Type: Bug
> Components: RM, webapp, yarn
> Affects Versions: 2.7.7
> Reporter: zhangjian
> Priority: Major
> Fix For: 2.8.5
>
>
> The YARN REST API can report on the following properties:
> *allocatedMB*: The sum of memory in MB allocated to the application's running
> containers
> *allocatedVCores*: The sum of virtual cores allocated to the application's
> running containers
> *runningContainers*: The number of containers currently running for the
> application
> But, the RM Web UI does not report on these items . I saw it's ok in
> hadoop2.8.5.
> It would be useful for YARN Application and Resource troubleshooting to have
> these properties and their corresponding values exposed on the RM WebUI.
